Four angles are formed by the intersection of the diagonals of this quadrilateral. which statement is not true?

a) ∠1 and ∠2 are adjacent.

b) m ∠2 = 180° – 120°

c) m ∠1 = 120° because ∠1 and the 120° angle are vertical angles.

d) m ∠1 = m ∠2

(D): m ∠1 = m ∠2

I got it correct, trust me.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
